综合物探技术在隐伏断层探测中的研究与应用

The research and application of comprehensive geophysical exploration technique to buried fault detection

对复杂地质环境中的隐伏断层探测是地球物理勘测中的一大难点。文中介绍了利用高密度电法、浅层地震反射波法和氡气测量法三种物探方法对隐伏断层进行综合探测的应用实例,并对这三种方法的勘探成果进行了分析,通过钻孔验证,达到了探测隐伏断层的目的。探测结果表明,综合物探方法在复杂地形条件下对隐伏断层的探测具有很大的优越性,具有可靠、方便和成果直观等特点。

The detection of buried fauh in complex geological environment is one of the difficulties in geophysical survey. This paper gives the application examples of three geophysical exploration methods to reveal buried fault comprehensively in somewhere of Mianyang. The methods are high-density resistivity method, shallow seismic reflection method and radon measurement . -And also the exploration results of three methods are analyzed, through the drilling data verification to reveal the buried fault. The detection results show that integrated geophysical exploi＇ation methods in complex topographical conditions in buried fault detection have great superiority such as reliability, convenience and intuitiveness etc.
